While the mystery surrounding Canada's gravitational anomalies has been put to rest, the study has wider implications. Scientists involved in the Harvard-Smithsonian Center study were amazed that they were able to see how the Earth looked 20,000 years ago. And by isolating the influence of the ice sheet's rebound effect, researchers better understand how convection affects gravity and how continents change over time. Finally, the GRACE satellites have provided scientists with data on many ice sheets and glaciers. By examining climate change that took place thousands of years ago, scientists may gain a better understanding of how global warming and rising sea levels are affecting our planet today and what impact they will have on our future.
